In this work, lead barium niobate tetragonal tungsten bronze structured ceramics modified with Gd3+ with the stochiometric formula Pbx-3y/2GdyBa1-xNb2O6, where y=0 – 10 mol% Gd3+, were fabricate through the solid state reaction method and investigated for structural and Raman properties. The dried powders were calcined at 800°C for 6h and one sample was calcined at 1050°C for 20h. As it can be observed, there is a mixture of tetragonal and orthorhombic phases. The analysis of the Raman spectra allowed a clear identification of the phase evolution Kinetics as a function of the calcining temperature.

Abstract
In this work, lead barium niobate tetragonal tungsten bronze structured ceramics modified with Gd3+ with the stochiometric formula Pbx-3y/2GdyBa1-xNb2O6, where y=0 – 10 mol% Gd3+, were fabricate through the solid state reaction method and investigated for structural and Raman properties. The dried powders were calcined at 800°C for 6h and one sample was calcined at 1050°C for 20h. As it can be observed, there is a mixture of tetragonal and orthorhombic phases. The analysis of the Raman spectra allowed a clear identification of the phase evolution Kinetics as a function of the calcining temperature.
